Circumference of the circle as 15 pi inches find the diameter
avanturin [10]

The formula for the circumference of the circle is 2πr or πd with r being the radius and d being the diameter. These 2 gives the same result because d=2r

Now because we know that the circumference is 15pi, we just need to reverse to find the diameter.

π*diameter=15*π

We can divide π from both sides.

diameter=15

Hope this helped!

Ray MO bisects LMN LMO = 6x-20 and NMO =2x+36. solve for x and find LMN
mestny [16]
6x - 20 = 2x + 36
6x - 2x = 36 + 20
4x = 56
x = 56/4
x = 14

m∠LMN = 6x - 20 + 2x + 36 = 8x + 16 = 8 * 14 + 16 = 128°
